The good news is that it is really simple to make.
Took me a long time to drill a hole at the tip end of the saw (hand drill and cheapish drill bit...) but the rest is very fast to make.
First I thought of a larger (about 1") strip of aluminium than came up with the idea of combining the padding to make the handle with the needed cover for the blade when stored so opted for the smaller 10mm x 3mm strip.
